57 Nomad-C4-LS1 called "Ozzy"

Sounds like you're making progress Paul. Glad you got that engine positioning corrected. I just wondered why you moved it forward if you were replacing the firewall anyhow.

Also, I put my ECU inside the console, and have almost no wiring showing in the engine compartment.

If I pass the wiring thru the firewall, it's 70 wires. Seventy... Nobody makes a plug that handles even half that.
I want to be able to unplug the wires so painting and reassembly is a snap. Looking for the right place to pass that many wires thru without making it so obvious.

I have something like 36 wires going to my engine. I just put a grommet in the hole, and passed the wires through it. I can unplug the harness from the engine and pull it back into the inside of the car, I believe. There is some sort of connector or terminal on every wire to the engine.

I found this.

How much does that little baby cost?

[WagonCrazy]

Google search on Deutch DRB128 connector turns up all kinds of sites selling it and NOT ONE OF THEM shows a price.
Guess it's whatever they think you'll pay when you have to call in and inquire...

The firewall hole needed for this connector would be big enough to pass the whole ECU connector thru with all the wires attached. Granted, I'd have to figure out a way to seal it with all the wires passing thru, but I'll bet this little pupply goes for over $100. Too spendy for me...

I was thinking it wouldn't be cheap either.

[chevynut]

Why are there 70 wires? Do you really need them all? I re-wired my Holley C950 ECU and took out some unused wires. You should only have about 6 sensors, 8 injector wires (mine are batch fired 2x4) and some ignition wiring (coils, knock sensor, etc.), AC, Alternator, and fuel pump control. Is there a separate wire to each coil?

I was just wondering if perhaps some of those wires could be deleted.

[Rick_L]

I don't know about the deletions, but many of the wires you mention don't have to go through the firewall anyway, do they? Especially if you have an underhood fuse/relay center. I guess that ends up in the passenger compartment if you're very vain about hiding stuff, but there's other places too (inner fenders/compartments).

[WagonCrazy]

It could be possible to delete a few wires, but most of them seem necessary. Many of those sensors and injectors have 2 or more wires each. As for ecu mount location, was trying to mount it in the center console behind the shifter but thats just a stink load of wires to put thru the firewall somewhere, so am considering moving it to engine compartment inner fender well area somewhere.
Main fuse panel will go behind the rear bench seat in a new bulkhead seat back area I'm going to fab up soon. Battery and stereo amp and bass speaker will go in there also. I'm planning a secondary fuse-relay panel in the engine compartment also. Haven't yet crystallized on the overall wiring strategy just yet. So many variables to consider.
